Well, opals are a very beautiful gem, and quite valuable. They are actually remains of ancient, fossilized beings, and have qualities that diamonds do not have, and unlike diamonds, which can be created in a lab, are very unique. Australia is very well known for it's opal mining systems. My source: the Opal Museum in Sydney, Australia.

Opal's weight can vary depending on its type and water content, but it generally has a specific gravity of about 1.98 to 2.20. This means that opal is lighter than many other gemstones, such as diamonds or sapphires. The weight of a specific opal piece can be determined by its size and density, with common sizes ranging from a few carats to several hundred carats.
A created opal is a type of synthetic opal that is made in a laboratory. It is created using a combination of silica spheres and a polymer resin material to mimic the appearance of natural opal. Created opals can display similar color play and patterns to genuine opals.
Kind of sounds like a 'floating opal'. It is a glass globe filled with multi-coloured opal chips and oil - the oil brings out the colour and keeps the opal from crazing. If it is a floating opal, they are mostly considered antiques now but there is at least one company that still produces them - they can be found with an Ebay search.
